x86/mce: Fix check for processor context when machine check was taken.
commit 875e26648cf9b6db9d8dc07b7959d7c61fb3f49c upstream.
Linus pointed out that there was no value is checking whether m->ip
was zero - because zero is a legimate value. If we have a reliable
(or faked in the VM86 case) "m->cs" we can use it to tell whether we
were in user mode or kernelwhen the machine check hit.
